Why liara_manage_databases needs a policy

This tool explicitly includes 'delete' as one of its operations on databases. Deleting a database is an irreversible destructive action with critical blast radius — it can permanently destroy all stored data. The tool also includes other severe operations like stop/restart which can cause service outages.

From the tool's definition Database lifecycle management: list, get details, create, delete, start, stop, restart, or resize databases

POLICY

How to control liara_manage_databases

PolicyLayer is an MCP gateway — it sits between your AI agents and Liara MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for liara_manage_databases:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "liara_manage_databases"
  ]
}

liara_manage_databases disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register Liara MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
